Description

Technical Field

[0001] This specification relates to the field of building energy conservation, and particularly to an energy-saving window curtain based on solar energy. Background Art

[0002] With the increasing energy shortage, the goals of carbon peak and carbon neutrality are imperative. Among the total existing buildings in China, the carbon emissions from building operation account for about 21% of the total carbon emissions. Therefore, improving building energy-saving technology is the key means to achieve carbon peak and carbon neutrality. In the building structure, the transparent part of the building structure (such as windows) is an important part of the building, and it is the most active and sensitive part of the building's heat exchange and heat conduction. The main ways of energy loss through the transparent part of the building are heat conduction, heat convection, and heat radiation. In a building, the heat exchange through windows is 5 to 6 times that through walls. According to statistics, the energy consumption generated through the transparent part of the building accounts for more than 50% of the total energy consumption of the whole building. Therefore, the research on energy-saving means for the transparent part of the building has received increasing attention. The existing sealed window curtains can eliminate the gaps between the window curtain and the wall and prevent heat from entering the room through the gaps, but they cannot prevent heat from entering the room through the windows and the window curtain by means of heat exchange and heat conduction, thus affecting the energy consumption of the building.

[0003] Therefore, there is a need to provide an energy-saving window curtain based on solar energy, which can not only eliminate the gaps between the window curtain and the wall, but also prevent heat from entering the room through the windows and the window curtain by means of heat exchange and heat conduction without increasing carbon emissions, thereby improving the energy-saving and emission-reduction effects. Summary of the Utility Model

[0004] This specification provides an energy-saving window curtain based on solar energy, which can not only eliminate the gaps between the window curtain and the wall, but also prevent heat from entering the room through the windows and the window curtain by means of heat exchange and heat conduction without increasing carbon emissions, thereby improving the energy-saving and emission-reduction effects.

[0005] This specification provides an energy-saving window curtain based on solar energy, which is used to be installed on a target window equipped with a window. It includes a window curtain device and a heat dissipation device. When in use, the window curtain device is installed on one side of the window, connected to the fixed surface around the target window, and can move to change the area covering the target window. When the window curtain device fully covers the target window, a sealed connection is formed between the window curtain device and the fixed surface, and a sealed cavity is formed between the window curtain device and the window. And the heat dissipation device is installed on the window curtain device, located between the window and the window curtain device, and includes a cooling device and a solar device. The cooling device is installed on the window curtain device and cools the sealed air between the window and the window curtain device during operation to reduce the temperature of the sealed air. The solar device is installed on the window curtain device, electrically connected to the cooling device, and converts solar energy into electrical energy to supply power to the cooling device.

[0006] In some embodiments, the heat dissipation device further includes a control device, which is installed on the window curtain device and is communicatively connected to the cooling device during operation to control the start and stop of the cooling device.

[0007] In some embodiments, the heat dissipation device further includes at least one position sensor, which is installed on the window curtain device and is communicatively connected to the control device during operation to detect the position of the window curtain device and send position data to the control device to determine whether the window curtain device fully covers the target window. Among them, when the window curtain device fully covers the target window, the control device controls the cooling device to start.

[0008] In some embodiments, the heat dissipation device further includes at least one temperature sensor, which is installed on the window curtain device and is communicatively connected to the control device during operation to monitor the temperature data of the sealed air and send the temperature data to the control device. Among them, when the window curtain device fully covers the target window and the temperature of the sealed air is higher than the set temperature threshold, the control device controls the cooling device to start.

[0010] In some embodiments, the cooling device includes a thermoelectric cooler and a fan. The thermoelectric cooler is installed on the curtain device and is electrically connected to the solar device. It includes a refrigerating end and a heating end. During operation, the heat at the refrigerating end is transferred to the heating end, thereby reducing the temperature of the refrigerating end. The fan is installed on the curtain device and, during operation, sends the low-temperature air at the refrigerating end into the sealed cavity between the window and the curtain device to cool the sealed air.

[0011] In some embodiments, the air inlet of the fan faces the refrigerating end, and the air outlet of the fan faces the sealed air.

[0012] In some embodiments, the fan includes an air inlet facing indoors or outdoors; a first air outlet facing the refrigerating end and the sealed cavity to cool the sealed cavity; a second air outlet facing the heating end and the sealed cavity to heat up the sealed cavity; and a damper assembly configured to control the opening and closing of the first air outlet and the second air outlet.

[0013] In some embodiments, the damper assembly includes a damper and a driving motor. The damper is movably arranged at the first air outlet and the second air outlet. The driving motor is configured to control the movement of the damper between a first position and a second position. When the damper is in the first position, the damper blocks the first air outlet and opens the second air outlet. When the damper is in the second position, the damper blocks the second air outlet and opens the first air outlet.

[0014] In some embodiments, the damper includes: a first damper movably arranged at the first air outlet; a second damper movably arranged at the second air outlet. The driving motor includes: a first driving motor configured to control the opening and closing of the first damper; a second driving motor configured to control the opening and closing of the second damper.

[0015] In some embodiments, heat-conducting fins are provided at the refrigerating end.

[0016] In some embodiments, the heat dissipation device further includes a power supply device installed on the curtain device and electrically connected to the cooling device and the solar device respectively to absorb the electric energy of the solar device and supply power to the cooling device.

[0017] In some embodiments, the heat dissipation device further includes a thermoelectric power generation device installed on the curtain device and electrically connected to the power supply device, configured to absorb the heat at the heating end and convert the heat into electric energy to charge the power supply device.

[0018] In some embodiments, the thermal energy power generation device includes a heat storage device and a thermoelectric power generation device. The heat storage device is connected to the heating end, and absorbs and stores the heat from the heating end during operation. The first end of the thermoelectric power generation device is connected to the heat storage device, and the second end is electrically connected to the power supply device. When the heat stored in the heat storage device reaches a preset value, the heat storage device releases the heat to the first end to increase the temperature of the first end, and the thermoelectric power generation device generates electric energy under the temperature difference between the first end and the second end to charge the power supply device.

[0019] In some embodiments, the heat storage device includes a heat storage unit, which includes a phase change material. During operation, the phase change material absorbs the heat from the heating end, thus undergoing a phase change and storing the heat.

[0020] In some embodiments, the window curtain device includes a fixed frame, a movable frame, and the curtain. The fixed frame is connected to the fixed surface around the target window during use; the movable frame is disposed opposite to the fixed frame and can be opened and closed relative to the fixed frame; the curtain is located between the fixed frame and the movable frame and can move between a first position and a second position to change the area covering the target window. When the curtain is in the second position, the target window is fully blocked. When the curtain is in the second position, the movable frame is closed with the fixed frame and clamps the curtain, so as to form a sealed connection between the curtain and the fixed surface of the target window.

[0021] In some embodiments, the solar energy device includes a solar panel, which is made of a flexible material and attached to the outdoor-facing surface of the curtain.

[0022] In some embodiments, the heat dissipation device includes a housing, and the fan is disposed inside the housing. The housing includes a fresh air inlet configured to communicate with the outside; a fresh air outlet configured to communicate with the inside; a ventilation opening configured to communicate with the sealed cavity; and a fresh air damper configured to open and close the fresh air outlet. The air inlet of the fan communicates with the fresh air inlet, and the air outlet of the fan communicates with the fresh air outlet and the ventilation opening respectively.

[0023] In some embodiments, the fresh air damper is disposed between the fresh air outlet and the ventilation opening, and is configured to move between a fresh air open position and a fresh air closed position. When the fresh air damper is in the fresh air open position, the fresh air damper opens the fresh air outlet and closes the ventilation opening; when the fresh air damper is in the fresh air closed position, the fresh air damper closes the fresh air outlet and opens the ventilation opening.

[0024] In some embodiments, an air filtration module is provided at the fresh air inlet and / or the fresh air outlet.

[0025] In some embodiments, the air filtration module includes one or several of a photocatalyst layer, an activated carbon layer, and a sponge layer that are stacked.

[0026] As can be seen from the above technical solutions, for the energy-saving window curtain based on solar energy provided in this specification, a heat dissipation device is provided between the window curtain device and the window, and the solar energy device is used to supply power to the heat dissipation device. When the window curtain device completely covers the target window, a sealed connection is formed between the window curtain device and the target window. The cooling device in the heat dissipation device can cool the enclosed air between the window curtain device and the window to reduce the temperature of the enclosed air. When the temperature sensor senses that the temperature of the enclosed air rises, the control device controls the cooling device to start to reduce the temperature of the enclosed air. Although the heat outdoors still heats the air in the enclosed cavity through the window, the cooling device always controls the air in the sealed cavity to be the same as or close to the indoor temperature. Then, the heat of the outdoor air is cooled in advance by the enclosed air in the sealed cavity when it is transferred to the sealed cavity, and the temperature of the indoor environment will not rise, thereby reducing the energy consumption generated by the transparent part of the building and improving the energy conservation and emission reduction effect. In addition, since the solar energy device is used to convert solar energy into electric energy to supply power to the cooling device, the power source of the heat dissipation device comes from renewable solar energy. Compared with the heat dissipation device driven by ordinary electric energy, the carbon emission is reduced, and the energy conservation and emission reduction effect is further improved.

According to the description, the content introduced by the following numbers and examples will be obvious to those of ordinary skill in the art.

[0041] The following description provides specific application scenarios and requirements of the present specification, aiming to enable those skilled in the art to manufacture and use the content in the present specification. For those skilled in the art, various partial modifications to the disclosed embodiments are obvious, and without departing from the spirit and scope of the present specification, the general principles defined here can be applied to other embodiments and applications. Therefore, the present specification is not limited to the shown embodiments, but covers the broadest scope consistent with the claims.

[0042] The terms used herein are for the purpose of describing particular example embodiments only and are not limiting. For example, unless the context clearly dictates otherwise, as used herein, the singular forms "a", "an" and "the" may also include the plural forms. When used in this specification, the terms "comprising", "including" and / or "containing" mean that the associated integers, steps, operations, elements and / or components exist, but do not preclude the existence or addition of one or more other features, integers, steps, operations, elements, components and / or groups.

[0043] In view of the following description, these and other features of the present specification, as well as the operations and functions of the related elements of the structure, and the combination and manufacturing economy of the components can be significantly improved. Referring to the accompanying drawings, all of which form a part of this specification. However, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not drawn to scale.

[0044] This specification provides an energy-saving window curtain 001 based on solar energy. Figure 1 A side view of an energy-saving window curtain 001 based on solar energy provided according to an embodiment of this specification is shown. For ease of description, we can define the Z direction as upward, the opposite direction of the Z direction as downward, the Y direction as the front, the opposite direction of the Y direction as the back, the X direction as the left, and the opposite direction of the X direction as the right.

[0045] The solar energy-based energy-saving window curtain 001 can be attached to the target window 003 on a building or other man-made structure to block the light channel formed by the target window 003. For example, the solar energy-based energy-saving window curtain 001 can be installed on the fixed surface around the target window. The building can be any form of building, such as an office building, a residential building, a self-built house, a multi-story building, and so on. In some embodiments, the other man-made structure can be a vehicle, such as a car, a public transportation vehicle, such as a train, a bus, and so on, and even can be an airplane. The target window 003 can be an opening or a light channel on the building or the other man-made structure for allowing light or air to enter a certain space (such as indoors or inside the vehicle). In some embodiments, a glass window 002 can be installed on the target window 003. The window 002 can divide the space into two parts: indoors and outdoors. When the window 002 is closed, the indoors and the outdoors are separated by the window 002 and the air cannot circulate. For the convenience of description, we define the Y direction as the indoor side and the opposite direction of the Y direction as the outdoor side. The target window 003 can be an opening or a light channel of any shape, such as a rectangle, a circle, a rounded rectangle, a semi-circle, and so on. For the convenience of description, we will describe it by taking the target window 003 as a rectangle as an example. The target window 003 can include a fixed surface 004 and a window hole surrounded by the fixed surface 004. The window hole is a channel for light to pass through. The fixed surface 004 can include 4 installation surfaces, surrounding the target window 003 and jointly forming the target window 003.

[0046] Such as Figure 1As shown, the solar-based energy-saving window curtain 001 may include a window curtain device 1000 and a heat dissipation device 2000. When in use, the window curtain device 1000 can be installed on one side of the window 002. In some embodiments, the window curtain device 1000 can be installed on the indoor-facing side of the window 002. In some embodiments, the window curtain device 1000 can be installed on the outdoor-facing side of the window 002. For the convenience of display, in the following description, we will take the example of the window curtain device 1000 being installed on the indoor-facing side of the window 002 for description. When installed, the window curtain device 1000 can be connected to the fixing surface 004 around the target window 003. When in use, the window curtain device 1000 can move to change the area covering the target window 003. When the window curtain device 1000 fully obscures the target window 003, a sealed connection can be formed between the window curtain device 1000 and the fixing surface 004, eliminating the gap between the window curtain device 1000 and the target window 003, so that the air between the two sides of the window curtain device 1000 within the target window 003 can neither flow through the gap between the window curtain device 1000 and the target window 003 nor through the window curtain device 1000 itself, thereby isolating the air circulation between the two sides of the window curtain device 1000 within the target window 003, reducing heat transfer caused by air circulation, improving the energy-saving effect, and at the same time blocking impurities such as mosquitoes and dust.

[0047] The heat dissipation device 2000 can be installed on the window curtain device 1000 and is located between the window 002 and the window curtain device 1000. As mentioned above, when the window curtain device 1000 fully obscures the target window 003, a sealed connection can be formed between the window curtain device 1000 and the fixing surface 004. At this time, a sealed cavity is formed between the window 002 and the window curtain device 1000. To prevent the heat on the outdoor side from being transferred to the indoor through the window 002, the enclosed air in the sealed cavity, and the window curtain device 1000 by heat conduction, the heat dissipation device 2000 can cool the enclosed air in the sealed cavity to reduce the temperature of the enclosed air and prevent the heat of the window 002 from being transferred to the window curtain device 1000 and the indoor through the enclosed air.

[0048] Figure 2 Shows a schematic diagram of the diagonal structure of a window curtain device 1000 provided according to an embodiment of the present specification; Figure 3 Shows an exploded schematic diagram of a window curtain device 1000 provided according to an embodiment of the present specification. As Figures 2 to 3 shown, the window curtain device 1000 may include a fixed frame 200, a movable frame 400, and a curtain 600. In some embodiments, the window curtain device 1000 may further include a connection structure 800. In some embodiments, the window curtain device 1000 may further include a transmission mechanism 900.

[0049] The window curtain device 1000 can be installed on the target window 003 (for example, the window curtain device 1000 can be installed on the fixed surface around the target window), so as to partially or completely block the target window 003. When the window curtain device 1000 is in the first position, the window curtain device 1000 is fully opened, allowing light to pass through the target window 003; when the window curtain device 1000 is in the second position, the window curtain device 1000 is fully closed, completely blocking the target window 003. The position of the window curtain device 1000 can move between the first position and the second position to change the coverage area or the blocked area of the window curtain device 1000 on the target window 003. For the convenience of description, we define the direction formed by the first position and the second position as the target direction. That is, the target direction can be the direction pointing from the first position to the second position or the direction pointing from the second position to the first position. In some embodiments, the target direction can be the direction where the Z-axis is located, that is, the up-down direction. In some embodiments, the target direction can be the direction where the X-axis is located, that is, the left-right direction. For the convenience of display, we will describe it with the target direction being the direction where the Z-axis is located, that is, the first position and the second position can be above and below the target window 003 respectively.

[0050] As Figures 2 to 3 shown, when in use, the fixed frame 200 can surround the window hole and be fixedly connected to the fixed surface 004 around the window hole. The outer edge of the fixed frame 200 can match the shape and size of the target window 003. Taking the target window 003 as a rectangle as an example, the fixed frame 200 can also be a rectangle. In some embodiments, the fixed frame 200 and the fixed surface 004 can be sealed with a sealing material, such as rubber, sealant, foam cotton, and so on.

[0051] In some embodiments, the fixed frame 200 can further include a first magnetic body 280, such as a first magnetic strip. The first magnetic body 280 can be a device with magnetism and can generate an adsorption force. In this specification, the first magnetic body 280 can be arranged on the side of the fixed frame 200 pointing in the Y direction (i.e., the front side).

[0052] As Figures 2 to 3As shown, when the movable frame 400 is in operation, it can be disposed opposite to the fixed frame 200 and movably connected to the fixed frame 200 to open and close parallel to the fixed frame 200. The movable frame 400 can be movably connected to the fixed frame 200 in any manner so that the movable frame 400 can translate relative to the fixed frame 200 to change the distance between the movable frame 400 and the fixed frame 200, causing the movable frame 400 to approach or move away from the fixed frame 200. When the movable frame 400 approaches the fixed frame 200 and contacts and closes with the fixed frame 200, a seal can be formed between the movable frame 400 and the fixed frame 200. When the movable frame 400 moves away from the fixed frame 200 and opens with the fixed frame 200, a gap can exist between the movable frame 400 and the fixed frame 200.

[0053] In some embodiments, the movable frame 400 may further include a second magnetic body 480. The second magnetic body 480 can be a device with magnetism and can generate an adsorption force with the first magnetic body 280. The second magnetic body 480 can be disposed opposite to the first magnetic body 280. When the window curtain device 1000 is in the second position, the movable frame 400 approaches the fixed frame 200 under the adsorption force of the first magnetic body 280 and the second magnetic body 480 and closes relative to the fixed frame 200. In this specification, the second magnetic body 480 can be disposed on one side (i.e., the reverse side) of the movable frame 400 pointing in the opposite direction of the Y direction.

[0054] As Figures 2 to 3 shown, the window curtain device 1000 may further include a connection mechanism 800. The connection mechanism 800 can be connected to the fixed frame 200 and the movable frame 400. The movable frame 400 can be indirectly connected to the fixed frame 200 through the connection mechanism 800, and under the action of the connection mechanism 800, the movable frame 400 and the fixed frame 200 achieve the movable connection.

[0055] In some embodiments, the connection mechanism can be a four-bar linkage mechanism. At this time, the connection mechanism 800 can include at least two connecting rods 820, which are distributed at different positions. Both ends of each connecting rod 820 are respectively hinged to the fixed frame 200 and the movable frame 400, thus forming a four-bar linkage mechanism, enabling the movable frame 400 to open and close parallel to the fixed frame 200. As Figures 2 to 3 shown, 3 connecting rods 820 are shown. Those skilled in the art should understand that the number of connecting rods 820 being 2 or more than 2 is within the protection scope of this specification. In some embodiments, the connection mechanism 800 can also be a link-slider mechanism, or a slider guide mechanism, etc.

[0056] As Figures 2 to 3As shown, the curtain 600 can be located between the fixed frame 200 and the movable frame 400, and move between the first position and the second position to change the area covering the target window 003. When the curtain 600 is in the second position, the target window 003 is fully blocked. Among them, when the curtain 600 is in the second position, the movable frame 400 approaches the fixed frame 200 and closes relative to the fixed frame 200 to clamp the curtain 600, so as to form a sealed connection between the curtain 600 and the fixed surface 004 of the target window 003, so that the air between the two sides of the curtain 600 inside the target window 003 cannot flow through the gap between the curtain 600 and the target window 003. At the same time, sunlight cannot pass through the gap between the curtain 600 and the target window 003 through the window curtain device 1000, so as to reduce the heat transfer caused by air circulation, improve the energy-saving effect, and at the same time block impurities such as mosquitoes and dust.

[0057] The curtain 600 can be made of any light-shielding material, which can be non-transparent, or can be a transparent or semi-transparent light guide material. The light shielding can block some or all of the light in the light to prevent it from passing through the curtain 600. The light shielding can block a preset proportion of the light of a preset wavelength, such as reflecting ultraviolet rays, infrared rays, some visible light, and so on. In this application, the curtain 600 is taken as an example of a transparent light guide curtain. In some embodiments, the light guide curtain can be fully transparent or made of a medium that partially reflects and partially penetrates light. For example, the light guide curtain can reflect a preset proportion of the light of a preset wavelength, such as reflecting ultraviolet rays, infrared rays, some visible light, and so on. In some embodiments, the light guide curtain can include at least one transparent base film and at least one layer of partially reflective film. The partially reflective film can be attached to the transparent base film to reflect light of some wavelengths in the light. The light guide curtain can allow a preset proportion of visible light to pass through. For example, it can allow 0-0.1%, 1%, 2%, 5%, 7%, 8%, 10% of visible light to pass through, and so on. For example, the partially reflective film can be a metal coating of a predetermined thickness, such as an aluminum coating. The material and thickness of the partially reflective film can be changed according to the use requirements to change the light transmittance of the light guide curtain. The transparent base film can increase the perspective effect of the light guide curtain. In this way, users can see the scenery outside the window unobstructed through the light guide curtain, and can also use the light guide curtain to reflect a preset proportion of light, so that the indoor temperature will not be heated too high by the light, achieving an energy-saving effect.

[0058] In some embodiments, the light guide curtain can include multiple layers of partially reflective films. For example, the first layer of partially reflective film can be a polyester transparent layer to block ultraviolet rays, the second layer of partially reflective film can be a polyester metal coating to reflect the heat of sunlight, and the third layer of partially reflective film can be a polyester film layer to transmit visible light.

[0059] In some embodiments, the curtain 600 can be made of an airtight material, for example, the curtain 600 is a non-porous material. At this time, when the curtain 600 is in the second position, the movable frame 400 is closed relative to the fixed frame 200 to clamp the curtain 600, so as to form a sealed connection between the curtain 600 and the fixed surface 004 of the target window 003, so that the air between the two sides of the curtain 600 inside the target window 003 can neither flow through the gap between the curtain 600 and the target window 003 nor through the curtain 600 itself, thereby isolating the air circulation between the two sides of the curtain 600 inside the target window 003; at the same time, light cannot pass through the gap between the curtain 600 and the target window 003 through the window curtain device 1000, so as to reduce the heat transfer caused by air circulation, improve the energy-saving effect, and at the same time block impurities such as mosquitoes and dust.

[0060] In some embodiments, the window curtain device 1000 further includes a transmission mechanism 900. The transmission mechanism 900 can be directly or indirectly installed on the fixed surface 004. The transmission mechanism 900 can be connected to the curtain 600, and when running, it drives the curtain 600 to move between the first position and the second position under the action of an external force, changing the shielding area of the curtain 600 for the target window 003. The external force can be manual or electric, such as a driving motor.

[0061] In some embodiments, the window curtain device 1000 can also be any form of window curtain structure that can achieve sealing, such as a magnetic strip sealed window curtain, a magic tape sealed window curtain, a bayonet sealed window curtain, a lockable push-pull sealed window curtain, a sealable window curtain provided with a manual sealing structure, and so on. Those skilled in the art should understand that any form of window curtain device 1000 that can achieve a sealed connection between the window curtain device 1000 and the fixed surface 004 of the target window 003 is within the protection scope of this specification.

[0062] Figure 4 A front view of a heat dissipation device 2000 provided according to an embodiment of this specification is shown. Figure 4 The viewing direction of the shown heat dissipation device 2000 is the direction from the outdoor side to the indoor side. As Figure 4 As shown, the heat dissipation device 2000 can include a housing 2100, a cooling device 2200, and a solar device 2800. In some embodiments, the heat dissipation device 2000 can further include a power supply device 2300. In some embodiments, the heat dissipation device 2000 can further include a control device 2400. In some embodiments, the heat dissipation device 2000 can further include at least one position sensor 2500. In some embodiments, the heat dissipation device 2000 can further include at least one temperature sensor 2600. In some embodiments, the heat dissipation device 2000 can further include a thermoelectric power generation device 2900.

[0063] The housing 2100 can be the mounting base of the heat dissipation device 2000. The housing 2100 can be mounted on the curtain device 1000 and fixedly connected to the curtain device 1000. In some embodiments, the housing 2100 can be mounted on the fixed frame 200 of the curtain device 1000. In some embodiments, the housing 2100 can be mounted on the outer shell (the top box of the curtain device 1000) where the transmission mechanism 900 of the curtain device 1000 is located. In some embodiments, the outer shell where the transmission mechanism 900 of the curtain device 1000 is located can be used as the housing 2100. That is, the heat dissipation device 2000 and the curtain device 1000 can share the same housing 2100. In some embodiments, the housing 2100 can be mounted at any position of the curtain device 1000, such as the upper side, the lower side, the left side, the right side, and so on. For the sake of convenience of description, in Figure 1 and Figure 4 the figure shown, the housing 2100 is located on the upper side of the curtain device 1000. Those skilled in the art should understand that the housing 2100 mounted at other positions of the curtain device 1000 is also within the protection scope of this specification. In some embodiments, the housing 2100 can be detachably and fixedly mounted to the curtain device 1000, such as by screw connection, bayonet connection, and so on. In some embodiments, the housing 2100 can be fixedly connected to the curtain device 1000, such as by welding, riveting, bonding, and so on. In some embodiments, the housing 2100 can be integrally formed with the curtain device 1000. In some embodiments, the housing 2100 can include a whole. In some embodiments, the housing 2100 can include a plurality of independent sub-housings. The plurality of independent sub-housings can be mounted at any position of the curtain device 1000. For example, the number of the independent sub-housings can be two, which are respectively mounted on the upper side and the lower side of the curtain device 1000. Another example is that the number of the independent sub-housings can be four, which are respectively mounted on the upper side, the lower side, the left side, and the right side of the curtain device 1000. For the sake of convenience of description, we take the housing 2100 including two independent sub-housings as an example for description. The two independent sub-housings (the upper sub-housing and the lower sub-housing) are respectively mounted on the upper side and the lower side of the curtain device 1000. The upper sub-housing can be connected to the housing where the transmission mechanism 900 is located (the top box of the curtain device 1000). The lower sub-housing can be connected to the frame at the bottom of the fixed frame 200.

[0064] The cooling device 2200 can be installed on the housing 2100. In some embodiments, the cooling device 2200 can be installed outside the housing 2100. For example, it can be installed on one side of the housing 2100, such as the upper side, lower side, left side, right side, etc. In some embodiments, the cooling device 2200 can be installed inside the housing 2100. For the convenience of illustration, we will describe the case where the cooling device 2200 is installed on the upper sub-housing. Those skilled in the art should understand that the cooling device 2200 installed at other positions of the housing 2200 is also within the scope of protection of this specification. When the cooling device 2200 operates, it can cool the sealed air between the window 002 and the window curtain device 1000 to reduce the temperature of the sealed air. The cooling device 2200 can be directly or indirectly electrically connected to the solar device 2800 (such as indirectly electrically connected through the power supply device 2300) to obtain electrical energy from the solar device 2800 and provide the necessary energy for the operation of the cooling device 2200. As Figure 4 shown, the cooling device 2200 can include a thermoelectric cooler 2210 and a fan 2220.

[0065] The thermoelectric cooler 2210 can be installed on the housing 2100. In some embodiments, the thermoelectric cooler 2210 can be installed outside the housing 2100. For example, it can be installed on one side of the housing 2100, such as the upper side, lower side, left side, right side, etc. In some embodiments, the thermoelectric cooler 2210 can be installed inside the housing 2100. When the thermoelectric cooler 2210 operates, it can be directly or indirectly electrically connected to the solar device 2800 (such as indirectly electrically connected through the power supply device 2300) to obtain electrical energy from the solar device 2800. The thermoelectric cooler 2210 is a cooling device composed of semiconductors. The thermoelectric cooler 2210 includes a cooling end 2211 and a heating end 2212. Its working principle is that after power is applied, electrons start from the negative electrode (-), first pass through the P-type semiconductor (cooling end 2211), absorb heat here, and then release the heat at the N-type semiconductor (heating end 2212); every time an NP module is passed through, heat is transferred from the cooling end 2211 at one end to the heating end 2212 at the other end, so that the temperature of the cooling end 2211 drops to create a temperature difference. The cooling end 2211 and the heating end 2212 are respectively composed of two ceramic sheets.

[0066] The fan 2220 can be installed on the housing 2100. Specifically, the air inlet of the fan 2220 can face the cooling end 2211. The air outlet of the fan 2220 can face the sealed air. When the fan 2220 operates, it can send the low-temperature air at the cooling end 2211 into the sealed cavity between the window 002 and the window curtain device 1000 to cool the sealed air.

[0067] As Figure 5 shown, the air inlet of the fan 2220 can also face indoors or outdoors, and the air outlet of the fan 2220 faces the sealed air and the refrigerating end 2211. When the fan 2220 works, it can also send the low-temperature air at the refrigerating end 2211 into the sealed cavity between the window 002 and the window curtain device 1000 to cool the sealed air.

[0068] The above structure can be used in seasons with relatively hot weather to reduce the heat transfer from the outdoor hot air to the indoor. In addition, in seasons with relatively cold weather, in order to reduce the heat dissipation of the indoor hot air through the window 002 and the curtain 600 to the outside, the following structural design can be made for the window curtain device 1000:

[0069] As Figure 5 、 Figure 6 shown, the fan 2220 includes an air inlet 2221, a first air outlet 2222, a second air outlet 2223 and a damper assembly. Among them, the first air outlet 2222 faces the refrigerating end 2211 and the sealed cavity to send the low-temperature air at the refrigerating end 2211 into the sealed cavity between the window 002 and the window curtain device 1000 to cool the sealed air, so as to prevent the outdoor hot air from transferring heat to the indoor in seasons with relatively hot weather. In addition, the second air outlet 2223 faces the heating end 2212 and the sealed cavity to send the high-temperature hot air at the heating end 2212 into the sealed cavity between the window 002 and the window curtain device 1000 to heat the sealed air, so as to reduce the loss of indoor heat to the outside through the window and the curtain 600 in seasons with relatively cold weather. And, since a damper assembly is provided at the air outlet of the fan 2220, and the damper assembly can control the opening and closing of the first air outlet 2222 and the second air outlet 2223, therefore, the refrigerating or heating function of the window curtain device 1000 can be selected according to different needs, making the versatility of the window curtain device 1000 wider.

[0070] In a realizable manner of the damper assembly, the damper assembly can include a damper and a driving motor. The damper is movably arranged at the first air outlet 2222 and the second air outlet 2223; the driving motor is configured to control the movement of the damper between a first position and a second position. When the damper is in the first position, the damper blocks the first air outlet 2222 and opens the second air outlet 2223; when the damper is in the second position, the damper blocks the second air outlet 2223 and opens the first air outlet 2222. Thus, only one damper can be used to realize the switching between the refrigerating and heating functions of the window curtain device 1000, and the structure is simple and occupies little space.

[0071] For another example, the air door assembly can also use two air doors to separately control the opening and closing of the first air outlet 2222 and the second air outlet 2223. As Figure 5 , Figure 6 shown, the air door assembly includes a first air door 2224, a second air door 2225, a first driving motor, and a second driving motor (not shown in the figure). Among them, the first air door 2224 is movably arranged at the first air outlet 2222, and the first driving motor is used to drive the first air door 2224 to open and close. As Figure 5 shown, when the first air door 2224 is opened, the first air outlet 2222 faces the refrigeration end 2211 and the sealed cavity, so as to send the low-temperature air at the refrigeration end 2211 into the sealed cavity to cool the sealed air. The second air door 2225 is movably arranged at the second air outlet 2223, and the second driving motor is used to control the opening and closing of the second air door 2225. As Figure 6 shown, when the second air door 2225 is opened, the second air outlet 2223 faces the heating end 2212 and the sealed cavity, so as to send the high-temperature hot air at the heating end 2212 into the sealed cavity to heat the sealed air. Thus, two air doors and two driving motors are used to separately control the opening and closing of the first air door 2224 and the second air door 2225. Even if one of the air doors or one of the driving motors fails, it will not affect the normal use of the other air door or the other driving motor.

[0072] It should be noted that the movement of the above air door can be linear movement or rotation. When the air door adopts the linear movement scheme, a chute can be arranged on the inner wall of the air outlet of the fan 2220, so that the air door is slidably connected in the chute, and the driving motor controls the air door to linearly slide between the first position and the second position. Among them, the driving motor can adopt a linear motor or a rotary motor cooperating with a linear transmission mechanism to achieve. Among them, the linear transmission mechanism can convert the rotary motion of the motor output shaft into a linear motion. For example, the linear transmission mechanism can adopt a gear rack mechanism, a ball screw mechanism, etc., which is not limited here.

[0073] When the air door adopts the rotation scheme, the air door can be rotatably connected to the air outlet of the fan 2220 through a rotating shaft, and the driving motor controls the air door to rotate and switch between the first position and the second position. Among them, the driving motor can adopt a rotary motor or a rotary motor cooperating with a speed reduction mechanism to achieve. Among them, the speed reduction mechanism can reduce the rotation speed of the motor output shaft to prevent the air door from being damaged when the speed is too fast. The speed reduction mechanism can specifically adopt gear transmission, belt transmission or chain transmission, etc., which is not limited here.

[0074] As Figure 7As shown in the figure, in order to increase the contact area between the air outlet of the fan 2220 and the refrigeration end 2211, heat-conducting fins 2213 can be provided on the refrigeration end 2211 of the semiconductor refrigerator 2210, so that the heat-conducting fins 2213 are heat-transfer connected to the refrigeration end 2211. Thus, when the air outlet of the fan 2220 blows towards the refrigeration end 2211, it can fully contact the heat-conducting fins 2213 cooled by the refrigeration end 2211, thereby accelerating the cooling of the air outlet of the fan 2220 and avoiding energy waste, making the refrigeration effect better.

[0075] It should be noted that the above-mentioned fan 2220 can be an axial flow fan, a centrifugal fan, a cross-flow fan, etc., which is not limited herein.

[0076] Among them, the numbers of the semiconductor refrigerator 2210 and the fan 2220 can be adjusted according to actual usage requirements and space limitations. This specification does not limit this.

[0077] The cooling device 2200 can also be other types of equipment, such as a refrigerator, a condenser, etc.

[0078] In addition, the function of the fresh air system can also be integrated into the window curtain. Specifically, as Figure 10 shown, the semiconductor refrigerator 2210 and the fan 2220 of the cooling device are installed inside the housing 2100. A fresh air inlet (not shown in the figure), a fresh air outlet 2102, a ventilation opening 2103, and a fresh air damper 2104 can be provided on the housing 2100. Among them, the fresh air inlet is communicated with the outside; the fresh air outlet 2102 is communicated with the inside; the ventilation opening 2103 is communicated with the sealed cavity; the fresh air damper 2104 is used to open and close the fresh air outlet 2102. The air inlet 2221 of the fan 2220 is communicated with the fresh air inlet. The air outlets (the first air outlet 2222 and the second air outlet 2223) of the fan 2220 are communicated with the fresh air outlet 2102 and the ventilation opening 2103. Thus, when the fresh air function needs to be turned on, the fresh air damper 2104 can be controlled to open the fresh air outlet 2102, so that the air outlet of the fan 2220 is communicated with the inside, and thus the fresh air outside can be introduced into the room after the fan 2220 is turned on to improve the air quality in the room.

[0079] When using the fresh air function, if the temperature outside is too high or too low to be directly introduced into the room, the opening and closing of the first damper 2224 and the second damper 2225 can be controlled to select the cold end or the hot end of the semiconductor refrigerator 2210 to cool or heat the fresh air, so that the fresh air reaches a suitable temperature before entering the room. If the temperature outside is appropriate, the fresh air outside can be directly introduced into the room, and the power supply of the semiconductor refrigerator 2210 can be directly turned off to make it not work, and the fresh air outside can be directly introduced into the room, thereby saving energy. At this time, as Figure 12As shown, the first air damper 2224 and the second air damper 2225 can also be opened simultaneously to increase the air output.

[0080] Among them, the fresh air damper 2104 can be arranged between the fresh air outlet 2102 and the ventilation opening 2103, and can move between the fresh air open position and the fresh air closed position. When the fresh air damper 2104 is located at the fresh air open position, as Figure 10 shown, the fresh air damper 2104 opens the fresh air outlet 2102 and closes the ventilation opening 2103. Thus, when using the fresh air function, it can prevent fresh air from entering the sealed cavity, and make the fresh air directly enter the room from the fresh air outlet 2102, thereby shortening the introduction path of the fresh air and improving the efficiency of delivering fresh air to the room. When the fresh air damper 2104 is located at the fresh air closed position, as Figure 11 shown, the fresh air damper 2104 closes the fresh air outlet 2102 and opens the ventilation opening 2103. Thus, when not using the fresh air function, it can prevent the air output of the fan 2220 from entering the room, thereby improving the heat insulation efficiency of the window curtain.

[0081] It should be noted that the above fresh air damper 2104 can be manually controlled or automatically controlled by a driving member such as a motor, and is not limited here.

[0082] In order to filter the fresh air, as Figure 12 shown, an air filtration module 2105 can also be arranged on the introduction path of the fresh air. Specifically, the air filtration module 2105 can be arranged at the fresh air inlet or the fresh air outlet, or air filtration modules 2105 can be arranged at both the fresh air inlet and the fresh air outlet. Thus, the outdoor fresh air can be filtered and then introduced into the room to avoid impurities in the outdoor air from entering the room.

[0083] Specifically, the air filtration module can include one or several of a stacked filter mesh layer, a photocatalyst layer, an activated carbon layer, and a filter sponge layer. Among them, the filter mesh layer can filter larger impurities in the air, such as leaves. The photocatalyst layer can be used to decompose some organic compounds, some inorganic compounds, bacteria, viruses, etc. in the air. The activated carbon layer can be used to adsorb suspended particles, formaldehyde and other harmful substances in the air. The filter sponge layer can be used to adsorb excessive water vapor in the air.

[0084] The solar energy device 2800 can be directly and / or indirectly (such as through the housing 2100) installed on the window curtain device 1000, and is electrically connected to the cooling device 2200 directly or indirectly (such as through the power supply device 2300). When the solar energy device 2800 operates, it can absorb external solar energy and convert the solar energy into electrical energy to generate a required voltage and output current to supply power to the cooling device 2200. After the solar energy device 2800 stabilizes the voltage within a set range through the solar charging management module, it supplies power to the cooling device 2200 through the charging circuit. The solar energy device 2800 may include the solar charging management module and the charging circuit. As Figure 8 shown, the solar energy device 2800 may further include a plurality of solar panels 2801. The solar panels 2801 can be installed at any position between the window 002 and the window curtain device 1000 and face the outdoor side to absorb outdoor solar energy and convert it into electrical energy. For example, the solar panels 2801 can be installed on the fixed frame 200, for example, around the fixed frame 200. In some embodiments, the solar panels 2801 can also be installed on the indoor side of the window curtain device 1000 to absorb indoor light energy and convert the light energy into electrical energy. For example, the solar panels 2801 can be installed on the movable frame 400, for example, around the movable frame 400. For another example, as Figure 8 shown, the solar panels 2801 can also be installed on the outer surface of the housing 2100.

[0085] The solar panels 2801 can be thin-film solar panels 2801. In some embodiments, the solar panels 2801 can be crystalline silicon solar panels 2801. The installation position and quantity of the solar panels 2801 can be adaptively adjusted according to actual usage requirements, and the present specification does not limit this.

[0086] The solar panels 2801 can also be made of flexible materials. For example, amorphous silicon encapsulated by resin can be used as the main optoelectronic element layer and laid flat on the bottom plate made of flexible materials to make flexible solar panels 2801. The flexible solar panels 2801 can be bent and folded. As Figure 9 shown, the solar panels 2801 made of flexible materials can be attached to the curtain 600 and move between the first position and the second position together with the curtain 600. When the flexible solar panels 2801 are attached to the outdoor-facing surface of the curtain 600 and the curtain 600 is in the second position, the flexible solar panels 2801 can absorb outdoor solar energy and convert the solar energy into electrical energy to supply power to the cooling device 2200.

[0087] In summary, the solar energy device 2800 can make full use of renewable solar energy to power the cooling device 2200, providing the electrical energy required for the operation of the heat dissipation device 2000 while not increasing carbon emissions, saving energy consumption, and enhancing the energy-saving effect.

[0088] In some embodiments, the heat dissipation device 2000 may further include a power supply device 2300. The power supply device 2300 can be installed on the housing 2100. The power supply device 2300 can be electrically connected to the cooling device 2100 and the solar energy device 2800 respectively to store the electrical energy provided by the solar energy device 2800 and supply electrical energy to the cooling device 2100. The cooling device 2200 can obtain the electrical energy required for operation from the power supply device 2300. For example, the power supply device 2300 can be electrically connected to the semiconductor refrigerator 2210 to supply power to the semiconductor refrigerator 2210. In some embodiments, the power supply device 2300 can be directly electrically connected to the cooling device 2100. In some embodiments, the power supply device 2300 can be indirectly electrically connected to the cooling device 2100, for example, through the control device 2400, that is, the power supply device 2300 is electrically connected to the control device 2400, and the control device 2400 is electrically connected to the cooling device.

[0089] In some embodiments, the power supply device 2300 can be a renewable power supply device, such as a rechargeable battery, such as a storage battery, a dry battery, a lithium battery, etc., such as a low-voltage DC rechargeable lithium battery.

[0090] In some embodiments, the power supply device 2200 can also be directly or indirectly (through the control device 2400) electrically connected to the position sensor 2500 to supply electrical energy to the position sensor 2500. In some embodiments, the power supply device 2200 can also be directly or indirectly (through the control device 2400) electrically connected to the temperature sensor 2600 to supply electrical energy to the temperature sensor 2600. In some embodiments, the power supply device 2200 can also be directly or indirectly (through the control device 2400) electrically connected to the driving mechanism of the transmission mechanism 900 to provide power to the driving mechanism. The number of the power supply devices 2300 can be one or multiple. The power supply device 2300 can be installed at any position on the housing 2100. Specifically, the number and position of the power supply device 2300 can be adjusted and arranged according to the number and position of the devices (the cooling device 2200, the control device 2400, the position sensor 2500, the temperature sensor 2600, and the driving mechanism) electrically connected to the power supply device 2300. This specification does not limit this.

[0091] The control device 2400 can be installed on the housing 2100 and communicate with the cooling device 2200 during operation to control the start and stop of the cooling device 2200. Specifically, the control device 2400 can communicate with the semiconductor refrigerator 2210 to control the start and stop of the semiconductor refrigerator 2210. The control device 2400 can also be electrically connected to the power supply device 2300 to obtain electrical energy from the power supply device 2300. The control device 2400 can include a hardware device with data information processing functions and necessary programs required to drive the operation of the hardware device. In some embodiments, the control device 2400 can be a processor.

[0092] The control device 2400 can control the start and stop of the cooling device 2200 based on one or more methods. In some embodiments, the control device 2400 can control the start and stop of the cooling device 2200 based on a timing mode. For example, the start time and stop time of the cooling device 2200 can be preset in the control device 2400. The start time can be a time range, and the stop time can also be a time range. When the control device 2400 detects that the current time reaches the start time, it controls the cooling device 2200 to start; when the control device 2400 detects that the current time reaches the stop time, it controls the cooling device 2200 to stop. The start time and stop time can be automatically adjusted or manually adjusted according to environmental factors such as season, address, climate, orientation, and glass parameters of window 002 during use.

[0093] In some embodiments, the control device 2400 can control the start and stop of the cooling device 2200 based on a temperature control mode. For example, a temperature threshold for starting the cooling device 2200 can be preset in the control device 2400. When the control device 2400 detects that the current temperature is higher than the temperature threshold, it controls the cooling device 2200 to start; when the control device 2400 detects that the current temperature is lower than the temperature threshold, it controls the cooling device 2200 to stop. The temperature threshold can be automatically adjusted or manually adjusted according to environmental factors such as season, address, climate, orientation, and glass parameters of window 002 during use. The control device 2400 can detect the current temperature through the temperature sensor 2600. The temperature sensor 2600 will be described in detail in the following description.

[0094] In some embodiments, the control device 2400 can control the start and stop of the cooling device 2200 based on both the timing mode and the temperature control mode simultaneously.

[0095] As described above, when the curtain 600 reaches the second position and completely covers the target window 003, the fixed frame 200 and the movable frame 400 clamp the curtain 600, forming a sealed connection between the curtain 600 and the target window 003 and eliminating the gap between the curtain 600 and the target window 003. At this time, a sealed cavity is formed between the window curtain device 1000 and the window 002. The purpose of the cooling device 2200 is to cool the enclosed air in the sealed cavity, and it needs to be started after the window curtain device 1000 is in the second position and a sealed cavity is formed between the window curtain device 1000 and the window 002. Therefore, the control device 2400 can detect the position of the window curtain device 1000 to determine whether the window curtain device 1000 completely covers the target window 003. Only when the window curtain device 1000 completely covers the target window 003, the control device 2100 is controlled to start. Specifically, the control device 2400 can detect whether the window curtain device 1000 completely covers the target window 003 through the position sensor 2500. The position sensor 2500 will be described in detail in the following description.

[0096] In some embodiments, the control device 2400 can also be connected to the drive mechanism in the window curtain device 1000 to control the driving force of the drive mechanism.

[0097] In some embodiments, the heat dissipation device 2000 may further include at least one position sensor 2500. The number of the position sensors 2500 may be adjusted according to actual usage requirements. At least one position sensor 2500 may be installed on the curtain device 1000. When at least one position sensor 2500 operates, it may be communicatively connected to the control device 2400 to detect the position of the curtain device 1000 and send the position data to the control device 2400 to determine whether the curtain device 1000 fully shields the target window 003. When the control device 2400 determines that the curtain device 1000 fully shields the target window 003, the control device 2400 controls the cooling device 2100 to start. In some embodiments, the position sensor 2500 may be installed on the lower side of the curtain device 1000, for example, at the second position, to detect whether the curtain 600 is at the second position. The position sensor 2500 may be any sensor capable of measuring position, such as a distance sensor, for example, an infrared distance sensor, a radar distance sensor, a ultrasonic distance sensor, and so on. Again, an induction sensor, for example, an infrared induction sensor, a radar induction sensor, a ultrasonic induction sensor, and so on. Taking the position sensor 2500 being an infrared induction sensor as an example for description. The infrared induction sensor may be installed at the bottom of the fixed frame 200 and emit infrared rays in the direction of the indoor side of the curtain device 1000. When the curtain device 1000 is at the second position and fully shields the target window 003, the position data monitored by the infrared induction sensor will change. The control device 2400 may determine whether the curtain device 1000 fully shields the target window 003 based on the change in the position data of the infrared induction sensor.

[0098] In some embodiments, the position sensor 2500 may be installed at any position of the window curtain device 1000 to detect whether the curtain 600 is in the second position. The position sensor 2500 may be a magnetic body and a magnetic induction sensor, for example, a Hall sensor. The Hall sensor can sense the magnetic body and output sensed data (i.e., the position data). When the distance between the magnetic body and the Hall sensor is greater than a preset distance value, the Hall sensor cannot sense the magnetic body and outputs first position data. When the distance between the magnetic body and the Hall sensor is less than the preset distance value, the Hall sensor senses the magnetic body and outputs second position data. As described above, when the curtain 600 reaches the second position, the movable frame 400 approaches the fixed frame 200 and clamps the curtain 600 with the fixed frame 200. The magnetic body and the Hall sensor may be respectively installed at any positions on the fixed frame 200 and the movable frame 400, and the magnetic body and the Hall sensor are disposed opposite to each other. When the curtain 600 reaches the second position, the Hall sensor can sense the oppositely disposed magnetic body and output the second position data. The control device 2400 determines that the window curtain device 1000 fully shields the target window 003 based on the second position data.

[0099] In some embodiments, for example, in the above-mentioned timing mode, when the control device 2400 determines that the window curtain device 1000 fully shields the target window 003 through the position data of at least one position sensor 2500 and determines that the current time is within a preset time range (the time range corresponding to the start time), the control device 2400 may control the cooling device 2100 to start.

[0100] In some embodiments, the heat dissipation device 2000 may further include at least one temperature sensor 2600. The number of the temperature sensors 2600 may be adjusted according to actual usage requirements. The at least one temperature sensor 2600 may be installed on the housing 2100. Specifically, the at least one temperature sensor 2600 may be installed at any position on the housing 2100. In some embodiments, the temperature sensor 2600 may be installed between the window curtain device 1000 and the window 002 to measure the temperature of the sealed air between the window 002 and the window curtain device 1000. When the temperature sensor 2600 operates, it may be communicatively connected to the control device 2400, monitor the temperature data of the sealed air, and send the temperature data to the control device 2400. In some embodiments, the temperature sensor 2600 may be installed on the window curtain device 1000 and face the interior of the room to measure the temperature of the interior of the room and send the temperature data of the interior of the room to the control device 2400. In some embodiments, the temperature sensor 2600 may be installed both between the window curtain device 1000 and the window 002 and on the window curtain device 1000 and face the interior of the room. For the convenience of description, we will take the temperature sensor 2600 installed between the window curtain device 1000 and the window 002 to measure the temperature of the sealed air between the window 002 and the window curtain device 1000 as an example for illustration.

[0101] In some embodiments, for example, in the above temperature control mode, when the control device 2400 determines that the window curtain device 1000 fully shields the target window 003 based on the position data of at least one position sensor 2500, and determines that the temperature of the sealed air is higher than a set temperature threshold based on the temperature data monitored by at least one temperature sensor 2600, the control device 2400 may control the cooling device 2100 to start.

[0102] It should be noted that, in some embodiments, the start and stop of the cooling device 2100 may be controlled manually.

[0103] In some embodiments, the heat dissipation device 2000 may further include a thermoelectric power generation device 2900. The thermoelectric power generation device 2900 may be installed on the housing 2100. The thermoelectric power generation device 2900 may be electrically connected to the power supply device 2300 and configured to absorb the heat of the heating end 2212 and convert the heat into electrical energy to charge the power supply device 2300. The thermoelectric power generation device 2900 may include a heat storage device 2920 and a thermoelectric generator 2940.

[0104] The heat storage device 2920 can be connected to the heating end 2212 and absorb the heat of the heating end 2212 for storage during operation. Among them, when the heat stored in the heat storage device reaches a preset value, the heat storage device will release heat outward. The heat storage device 2920 can include a heat collection unit and a heat storage unit. Both ends of the heat collection unit can be respectively connected to the heating end 2212 and the heat storage unit to absorb the heat of the heating end 2212 and conduct the heat to the heat storage unit. The heat collection unit can conduct the heat evenly to the heat storage unit. In some embodiments, the heat collection unit can be a high-temperature and high-efficiency heat conduction material. In some embodiments, the heat collection unit can be a heat equalizing tube material.

[0105] The heat storage unit can absorb the heat transferred by the heat collection unit and store it. In some embodiments, the heat storage unit can be a device composed of a phase change material. In some embodiments, the interior of the heat storage unit is filled with a phase change material. When the heat of the heating end 2212 is transferred to the phase change material through the heat collection unit, the phase change material will absorb heat and undergo a phase change, and store the heat. The outer layer of the phase change material container is wrapped with a layer of heat insulation material to prevent heat dissipation. In some embodiments, a heat insulation material is arranged outside the phase change material. When the temperature outside the heat storage unit reaches the set heat release temperature, the phase change material in the heat storage unit will release the latent heat of phase change. The preset value can be the set heat release temperature. In some embodiments, the heat release temperature of a suitable phase change material can be selected according to the geographical location, the orientation of the building, and the glass parameters, so that it absorbs heat during the day and releases heat when the temperature drops to the set temperature at night. For example, the phase change material filled in the heat storage unit can be selected according to the local temperature. For example, after 10 o'clock in summer in Beijing, the temperature is about 22 degrees Celsius or above, and it will drop below 22 degrees Celsius at 6 pm. Therefore, the heat release temperature of the phase change material can be set to 22 degrees Celsius, so that it will absorb heat after 10 o'clock and the phase change material will release heat after 6 pm.

[0106] In some embodiments, the phase change material inside the heat storage unit is one or a mixture of paraffin, fatty acid, and crystalline water inorganic salt. In some embodiments, the melting point range of the phase change material inside the heat storage unit is a material in the range of 10 - 90 °C.

[0107] In some embodiments, the thermoelectric power generation device 2940 may be a thermoelectric power generation device made of a semiconductor material. According to the Seebeck effect, a voltage difference between two substances is caused by the temperature difference between two different electrical conductors or semiconductors. Therefore, when the two ends of the thermoelectric power generation device 2940 are simultaneously in contact with different temperatures, a current loop will be formed inside the thermoelectric power generation device 2940, and the greater the temperature difference, the stronger the generated current. Therefore, by generating a temperature difference at both ends of the thermoelectric power generation device 2940, the conversion between thermal energy and electrical energy can be achieved. The thermoelectric power generation device 2940 may include a first end and a second end. The first end may be connected to the heat storage device 2920, and the second end is electrically connected to the power supply device 2300. When the heat stored in the heat storage device 2920 reaches the preset value, the heat storage device 2920 releases the heat to the first end to increase the temperature of the first end; the thermoelectric power generation device 2940 generates electrical energy under the temperature difference between the first end and the second end to charge the power supply device 2300.

[0108] In some embodiments, the materials of the first end and the second end of the thermoelectric power generation device 2940 may be nanoporous thermoelectric materials. The thermoelectric materials are thermoelectric chips that are connected in series and arrayed in the power generation section. The thermoelectric chips are simultaneously in contact with a cold source and a heat source to generate a temperature difference and then start generating electricity, and then the electricity is led out through wires to charge the power supply device 2300. In some embodiments, multiple thermoelectric power generation devices 2940 may be provided to improve the charging efficiency.

[0109] In summary, in the thermal energy power generation device 2900, when the temperature of the sealed air is higher than the temperature threshold, the semiconductor refrigerator 2210 is started, and the sealed air is cooled through the refrigerating end 2211, and heat is generated at the heating end 2212. The heat at the heating end 2212 is transferred to the heat storage device 2920 and stored in the heat storage device 2920. When the heat stored in the heat storage device 2920 reaches the preset value, the heat is released outward, and electrical energy is generated through the thermoelectric power generation device 2940 to charge the power supply device 2300. For example, when the temperature is high during the day, the cooling device 2200 is started, and heat is stored in the heat storage device 2920; when the temperature drops at night, the cooling device 2200 stops, the heat stored in the heat storage device 2920 reaches the preset value, the heat storage device 2920 releases heat, a temperature difference is generated at both ends of the thermoelectric power generation device 2940, and the power supply device 2300 is charged. The thermal energy power generation device 2900 can make full use of the heat generated when the cooling device 2200 is working, and use the heat again to charge the power supply device 2300, so as to make full use of energy, reduce energy consumption, and improve the energy-saving effect.

[0110] In summary, by alternately charging the power supply device 2300 with the solar energy device 2800 and the thermal power generation device 2900, when there is solar energy, the solar energy device 2800 is used to charge the power supply device 2300. When there is no solar energy (such as at night) or the solar energy is insufficient, the thermal power generation device 2900 is used to utilize the heat generated during the operation of the cooling device 2200 to charge the power supply device 2300, so as to achieve continuous power supply.

[0111] In summary, for the solar energy-based energy-saving window curtain 001 provided in this specification, a heat dissipation device 2000 is provided between the window curtain device 1000 and the window 002, and the solar energy device 2800 and the thermal power generation device 2900 are used to supply power to the heat dissipation device 2000. When the window curtain device 1000 completely covers the target window 003, the cooling device 2200 in the heat dissipation device 2000 can cool the enclosed air between the window curtain device 1000 and the window 002 to reduce the temperature of the enclosed air. When the temperature sensor 2600 senses that the temperature of the enclosed air rises, the control device 2400 controls the cooling device 2200 to start to reduce the temperature of the enclosed air, so that the heat outside the window 002 cannot be conducted to the inner side of the window curtain device 1000 through the enclosed air, thereby preventing heat conduction and heat exchange between the window 002 and the window curtain device 1000. At the same time, by using renewable energy for power supply, carbon emissions are further reduced, and the energy conservation and emission reduction effect is improved. At the same time, the solar energy-based energy-saving window curtain 001 provided in this specification can absorb and store the heat generated during the operation of the cooling device 2300 through the thermal power generation device 2900, and charge the power supply device 2300 based on the heat, recycle and reuse the heat generated during the operation of the cooling device 2300, so as to make full use of energy, reduce carbon emissions, and improve the energy conservation effect.
